The U.S. International Trade Commission (ITC) has voted to institute an investigation of certain
automotive fuel caps and components thereof. The products at issue in this investigation are fuel caps
for use as original equipment by automobile manufacturers and for use as replacement parts in the
automotive aftermarket.

The investigation is based on a complaint filed by Stant Manufacturing, Inc., of Connersville, IN, on
January 28, 2005, alleging violations of section 337 of the Tariff Act of 1930 in the importation into
the United States, the sale for importation, and the sale within the United States after importation of
certain automotive fuel caps and components thereof that infringe patents owned by Stant. Stant filed
a motion for temporary relief along with its complaint. The complaint requests that the ITC issue a
temporary exclusion order and temporary cease and desist orders pending completion of the
investigation and a permanent exclusion order and permanent cease and desist orders upon a finding
of a violation of section 337.

The ITC has identified the following as respondents in this investigation:

By instituting this investigation (337-TA-532), the ITC has not yet made any decision on the merits of
the case. The case will be referred to the Honorable Sidney Harris, an ITC administrative law judge,
who will schedule and hold an evidentiary hearing. Judge Harris will make an initial determination as
to whether there is a violation of section 337; that initial determination is subject to review by the
Commission.

The ITC will determine whether to issue temporary exclusion or temporary cease and desist orders, or
both, within 90 days after institution of the investigation. The Commission will make a final
determination in the investigation at the earliest practicable time. Within 45 days after institution of
the investigation, the ITC will set a target date for completing the investigation. ITC remedial orders
in section 337 cases are effective when issued and become final 60 days after issuance unless
disapproved for policy reasons by the President of the United States within that 60-day period.
